Mortgage Broker vs Bank: Which Is Right for You?
A broker compares many lenders and is usually paid by the lender; your bank offers only its own products. Which wins depends on your situation, not a rule.
There’s no universal winner between a mortgage broker and your bank. A broker compares home loans across a panel of lenders and is usually paid by the lender that ends up writing your loan; your own bank offers only its own products, in a single relationship. Which one is right isn’t a rule you can look up. It’s a fit to your situation, and for some buyers going direct is perfectly sensible.
Brokers now facilitate a record 81.6% of new home loans, on the MFAA’s June 2026 quarter figures. That’s the share of loans they arrange, though, not proof that everyone needs one. This guide gives the two-sided answer a single provider’s own page, broker or bank, won’t usually lay out. It covers when a broker genuinely helps, when going direct is fine, and the trade-offs a one-sided page tends to skip. (Going direct means applying to a lender yourself, most often your own bank, but it can be any lender.)
If you’re still fuzzy on the role itself, start with what a mortgage broker does. Here we’re deciding something narrower: whether you actually need one.
- There’s no default winner. A broker compares many lenders across a panel; your bank offers only its own products (ASIC MoneySmart). Which wins depends on your situation, not a rule.
- A broker helps most when your finances are hard to compare: self-employed or casual income, a low deposit or scheme reliance, a credit blemish, a past decline. When your file is simple, strong and salaried with a solid deposit, going direct is often perfectly viable.
- Going direct isn’t “no expert”, and it can mean any lender, not only your own bank. Loyalty doesn’t guarantee a good price: the ACCC found borrowers with older loans often paid more than newer ones (ACCC, 2020), so compare current offers rather than assume.
- Using a broker is usually free to you because the lender pays, but “free” isn’t “no catch”: the panel isn’t the whole market, and the pay can tilt toward a bigger loan. Know the downside, then decide.
- Whichever way you lean, walk in with your own numbers so you can judge the offer, not just receive it.
Broker vs bank: the core trade-off
Strip away the sales pitch and the choice is simple to state. A broker gives you a comparison across a panel of lenders plus help getting the application through, and the lender pays them for arranging it (ASIC MoneySmart). Going direct means applying to a lender yourself and dealing with its own products and one relationship, with no broker in the middle. Your own bank is the most common direct option, but you can approach any lender, so the real choice is broker-arranged versus direct-to-a-lender, not broker versus your incumbent bank. Neither is “the expert versus no expert”; they’re two different ways to arrive at a loan.
One legal difference is worth putting up front. A broker owes you a best-interests duty and must prioritise your interests where they conflict with their own (ASIC RG 273) — an obligation a lender selling only its own products doesn’t carry. It’s a floor, not a promise of the whole market or the lowest rate, but it’s a real part of the comparison.
The market has swung hard toward the panel route: brokers facilitated 81.6% of new home loans in the June 2026 quarter, up from 53.9% in June 2018 (MFAA). That is the share of loans brokers arrange, not the share of buyers who need one, and it doesn’t tell you a broker got a better result for someone like you. Going direct isn’t wrong. For some buyers it’s the cleaner path.

When does a broker actually add value?
Here’s the honest answer: it depends on how hard your situation is to compare, and for a simple one it can be “not much.” A broker earns their keep when lender policies diverge and knowing which lender to approach is genuinely hard. When your file is straightforward and most lenders would treat it similarly, the comparison a broker runs (which the lender pays for) is one you could largely do yourself.
The table below is a rough map, not a verdict on your case. Match your situation to the row, then use it to decide how hard to look for a broker, or whether to approach a lender directly first.
| Your situation | How hard to compare lenders | Why | A reasonable lean |
|---|---|---|---|
| Simple, strong salaried income, clean file, solid deposit | Lower | Most lenders read a file like this similarly, so it’s easy to compare | Going direct is fine |
| Self-employed, casual, or multiple incomes | Higher | Which lenders accept your income type varies widely | A broker likely helps |
| Low deposit, or relying on a scheme | Higher | Only some lenders offer the scheme, and each applies its own credit policy | A broker likely helps |
| A credit blemish, or a prior decline | Higher | Who will assess you differently is hard to know from outside | A broker likely helps |
There’s no single answer to “are mortgage brokers worth it?” Worth is situational. The more your circumstances sit in the lower rows, the more a broker is doing work you’d struggle to do alone; the more you sit in the top row, the more a broker is a convenience rather than a necessity.
Is a broker really free, and does that settle it?
Mostly, yes on the first part. For most buyers a broker costs nothing directly, because the lender pays them for arranging the loan; a broker may also charge you a direct fee, but only in a written quote you sign first (ASIC MoneySmart). For the full breakdown of what a broker can and can’t charge, see what a broker actually costs you.
But “free” settles less than it seems. It removes the obvious objection (“won’t this cost me?”) without touching the real question: is the recommendation shaped by anything other than your interest? That’s where the downsides live, so it’s worth naming them plainly.
The costs and risks of using a broker
None of these is a reason to avoid a broker. They’re the things a one-sided page won’t usually lay out, and knowing them is how you use a broker well rather than passively.
- The panel isn’t the whole market. A broker can only place your loan with lenders they’re accredited to. An otherwise suitable or cheaper off-panel option may not appear in their comparison, so ask how many lenders they compare and who’s on the panel.
- The pay can tilt the advice, but a duty pulls back. A broker’s commission scales with loan size, and different lenders can pay different rates, which is a potential conflict to understand, not a claim about any one broker (how brokers get paid covers the mechanics). Against that sits the best-interests duty: a broker must weigh the options and be able to explain why the recommendation suits you. Ask which options they compared, including the lowest-cost suitable one, and why this is in your best interests.
- A recommendation isn’t a commitment. You can weigh a broker’s comparison and still decline the loan they suggest, or ask to see other options. And a “pre-approval” is conditional, not a promise the lender will approve or fund the loan; that still depends on income checks, your credit, the property valuation and the loan’s terms. If you feel pushed to apply or sign, treat it as a reason to slow down and check the costs, conditions and alternatives first.
- Mind the credit enquiries. Each loan application is recorded on your credit report, and too many in a short time can lower your credit score (ASIC MoneySmart). Talking to a broker isn’t itself an application, so ask exactly when a credit enquiry will be lodged, and with how many lenders, before anyone submits anything.
What about going direct to a lender?
Applying directly has real appeal, and your own bank is the obvious place to start. If you already bank somewhere you trust and your finances are straightforward, one relationship is simpler, and a lender may sharpen its offer to keep you. What loyalty won’t do is guarantee a competitive price. The ACCC’s 2020 home loan inquiry found borrowers with older loans were often paying more than those with newer ones, a gap it called a loyalty tax (ACCC, Home Loan Price Inquiry, 2020). That is a finding about existing loans over time, not proof that a new application to your own bank is priced worse. Read it as a reason to check current alternatives, not to rule the direct route in or out.
“I’ll just stay with my bank” is a convenience choice, not automatically a price win. If you go direct, do the one thing loyalty discourages: ask your bank for its best current rate as if you were a new customer, and check it against the market. Working out whether you’d even qualify elsewhere is its own question; how a single lender calculates your borrowing power explains what one bank weighs, and comparing how several lenders would weigh you is exactly what a broker adds.
So which should you choose?
Put your situation against the table, then pressure-test whichever way you lean. If you lean broker, ask what they compared and why this loan won. If you lean direct, ask your bank to price you as a new customer and sanity-check it against a couple of rivals. The decision isn’t broker-good, bank-bad; it’s which route gets you a loan you can defend on rate, fees and fit.
Get each loan’s Key Facts Sheet, the standard document every lender must provide, so you’re comparing like for like. To compare offers fairly, hold the basics constant (same loan amount, same type), then line them up on the same points: the interest rate and the comparison rate, upfront and ongoing fees, useful features like an offset or redraw, and any conditions or expiry dates. A comparison rate helps, but it may not match your exact loan, so run the numbers on your own figures. There’s also a middle path that isn’t broker-or-nothing: take a broker’s recommendation, then check one suitable option directly yourself before you commit. One caution either way: don’t lodge several applications just to compare, because each can leave a credit enquiry; line up indicative options first, and ask when an enquiry will actually be made.
The strongest position is to walk in already knowing your own numbers, so you can judge either party’s offer instead of taking it on trust.
knest.ai’s free Bank Match shows your indicative borrowing position and a shortlist of lenders to consider, with no credit check, so you can walk into a broker or your bank able to judge the offer rather than take it on trust.

The bottom line for buyers
There’s no default winner between using a broker and going direct. The right route depends on your circumstances and how much comparison and application help you want. A broker compares loans across its panel, which isn’t the whole market, and owes you a best-interests duty; go direct and you choose which lenders to approach, each offering its own products. A broker tends to add more where lender policies make your situation harder to compare; where your file is simple and strong, going direct is often enough.
Choose on your own circumstances, not on the broker share of new home loans or loyalty to one bank. A broker is usually paid by the lender, though some charge a direct fee, so ask how they’re paid, which lenders sit outside their panel, and why the recommendation suits you. Then, whichever route you take, compare the rate, the comparison rate, fees and features across more than one option before you commit.
Frequently asked questions
Is it better to use a mortgage broker or go straight to the bank?
There’s no universal answer, and “the bank” really means applying directly to a lender — your own bank is just the common example. A broker compares many lenders across a panel and owes you a best-interests duty; a lender you approach yourself offers only its own products. A broker tends to help more when your situation is hard to compare, and less when your income is a simple wage, your file is clean and your deposit is solid, where going direct is perfectly viable.
Are mortgage brokers worth it?
It depends on your situation, not on a rule. A broker is worth most when lender policies diverge and knowing which lender to approach is genuinely hard, such as self-employed or casual income, a low deposit, scheme reliance, or a past decline. For a straightforward salaried application, a broker is more a convenience than a necessity.
Do you pay more using a broker than going to the bank directly?
Usually you pay a broker nothing directly, because the lender pays them (ASIC MoneySmart). You’ll often read that your rate is identical either way, but that claim comes from the broking industry, not the regulator, so compare the actual loan on offer rather than assuming parity. And don’t assume loyalty to your own bank earns you a competitive price — the ACCC found older loans often cost more than newer ones (2020), which is a reason to check current alternatives.
Can a broker get me a better rate than my bank?
Sometimes, because a broker compares a panel of lenders rather than one. The best-interests duty they owe you requires a recommendation suited to your circumstances, but it doesn’t guarantee whole-market coverage or the lowest headline rate, and the panel isn’t the whole market. Treat a broker’s recommendation and a lender’s direct offer as two quotes to compare on rate, fees and fit, not as a settled winner.
